2002 electrical problems

[eriru]

the car has 56000 miles, everything worked perfect, until saturday.

It started with rear trunk ajar message, rear lights dont work, only center brake light, panic button on remote doesnt trigger horn, headlights are always on, if car is running, turn lights and hazzard dont work, dome light doesnt work, everything worked perfectly before, tried to reset by disconnecting battery, no luck, took it to a mechanic and said computer needs to be replaced, 900 dls, any ideas.

any one know where the rear trunk swithch is?

http://www.alldata.com/ They sell a years subscription for around $29.00 and they have good wiring diagrams. They tell you all ground locations. I would check these and if your going to check out circuits you will need good diagrams.
